Abstract

2918. Macnab, T. P. Feb. 5 Feed-motions; gearing, driving; lathes. - A change gearing for imparting motion to the back shaft of a lathe, or for connecting two parallel shafts in any machine, consists of two sets of wheels F, one set keyed on the feed-shaft S and the other set loose on a short driving-shaft A, but capable of being separately coupled to it by sliding the shaft longitudinally till a short key E engages a keyway in the desired wheel. The shaft is moved by a pinion B on a shaft C engaging a circular rack on the shaft A, the shaft C being continued through to the front of the lathe bed or to a convenient place, and having a band-wheel D with an index and locking-pin, so that the shaft A may be set to give the desired feed.
